LOCOMOTlVE-HEADLIGHT- the path some distance ahead,so as to secure a measure of safety both to the traveler and the person whose path leads across that of the engine.

- The invention contemplates a reflector of peculiar structure, the same being studded upon its inner side with a plurality of jewels or reflecting-surfaces, and means of novel formation for adjusting the headlight to different angles.

Fora full description of the invention and the merits thereof and also to acquire a knowledge of the details of construction of the means for'effecting the result reference is to be had to the following description and accompanying drawings.

While the invention may be adapted to different forms and conditions by changes in,

the structure and minor details without departin from the spirit or essential features thereo, still the preferred embodiment is shown in the accompanying drawings, in which Figure 1 'is a top plan view of a locomotiveengine provided with a headlight embodying the in'vention. Fig. 2 is a vertical central section of the headlight, showing the actuating means. Fig. 3 is a detail perspective view of a portion of the reflector. Fig. 4 is a detail view showing the headli ht applied to a traction or like engine and aving connection with the front axle, so as to move therewith.

Corresponding and like parts are referred to in the followin description and indicated in all the views 0 the drawings by the same reference characters.

The component parts comprising the headlight are suitably mounted, the reflector and burner being housed within a casing 1, having openings at or near the top for the escape of the hot airresulting from the burner. The reflector is of frusto-conical form and has a horizontal arrangement, the outer base being arranged foremost'and supplied with a double convex lens 2, whereas the smaller Specification of Letters Patent.

base is provided with a concave surface 3. The body of the reflector is preferably of metal, copper being preferred, and is polished upon its interior in the accustomed manner to provide a reflecting-surface.

A plurality of jewels 4 stud the entire surface of the reflector and are arranged in concentric and longitudinal rows. The jewels are shouldered, as shown most clearly in Fig. .3, and are fitted into openings 5, formed in the body of the reflector, the inner surfaces of the jewels projecting one-sixteenth of an inch, more or less, from the inner wall of the reflector.

The jewels may be retained in place by suitable means, such as mineral fabric 6 and awrapping of wire 7. A' burner Sis arranged within the smaller portion of the reflector and is supplied with oil from a tank 9 by means of a valve-pipe 10. A conical vent 11 is arranged at the top side of the. reflector in vertical alinement with the burner 10 and is surmounted by a second cone'12, the two cones of the vent controlling both the draft and light. The tank, burner, and reflector are located within the casing 5 and moved therewith in the angular adjustments of the headlight.

A table or supporting-platform '13 is arranged below the casing 1 and is provided in its top side with an annular groove which corresponds with a like groove formed in the lower side of a plate 'or base 14, secured to the bottom of the casing 1, a series of balls '15 being arranged in the matching grooves to v "the latter having connection, by means of a rod 18, with the crank portion of the crankshaft 16 and adapted to be actuated either by means of compressed air, steam, or other means. As shown, an operating-lever 19 is connected by rod 20 with the said valve, said lever being conveniently located to be readily accessible to the engineer. The tank 9 is preferably'mount'ed upon a spring'21, which admits of the ready removal of the tank from the casing when it is required to replenish it either with oil, gas, or other burning fluid.

It is to be understood that the style of burner fitted to the pipe 10 will depend upon the nature of the burning fluid, and in the case of oil the burner 8 will be of that type I for consuming oil, and for gas the burner S flector-hody adj aeent to and surrounding the will be of any "ariety commonly used in connection with gas-fixtures.

headlight is designated at 22, and 23 indicates the front axle of a traction-engine or like machine. Connections 24 of any design are interposed between the axle 23 and the openings thereof, and a covering enveloping the reflector and holding the jewels in place. 2.
